Fine/ultra-fine cohesive powders find application in different industrial and chemical sectors. For example, they are considered in the framework of the Carbon Capture and Storage (CCS), for the reduction of the carbon dioxide emissions to the atmosphere, and in the framework of the thermochemical energy storage (TCES) in concentrated solar power (CSP) plants. Therefore, developing of technologies able to handle/process big amounts of these materials is of great importance. In this context, the sound-assisted fluidized bed reactor (SAFB) designed and set-up in Naples represents a useful device to study the behavior of cohesive powders also in the framework of low and high temperature chemical processes, such as CO adsorption and Ca-looping. The present manuscript reviews the main results obtained so far using the SAFB. More specifically, the role played by the acoustic perturbation and its effect on the fluid dynamics of the system and on the performances/outcomes of the specific chemical processes are pointed out.
细/超细粘性粉末在不同的工业和化学领域有应用。例如，在碳捕获与封存（CCS）框架内，它们被用于减少向大气排放的二氧化碳；在聚光太阳能发电（CSP）厂的热化学储能（TCES）框架内也有应用。因此，开发能够处理/加工大量此类材料的技术非常重要。在此背景下，那不勒斯设计并搭建的声辅助流化床反应器（SAFB）是一种有用的装置，可用于研究粘性粉末在低温和高温化学过程（如CO吸附和钙循环）框架内的行为。本手稿综述了迄今为止使用SAFB获得的主要结果。更具体地说，指出了声扰动所起的作用及其对系统流体动力学以及特定化学过程的性能/结果的影响。
